RADIATOR.

1 b aZZ whom it may concern:

Be it known that I, LOUIS F. CLAUSING, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, haveinvented a new and useful Radiator, of which the following is a specification.

This invention relates to a radiator, and particularly pertains to a radiator of the cellular or honeycomb type employed in water cooling systems of internalcombus tion engines. I

In radiators of the above class, water is circulated through narrow passages and cooled by the action of air flowing in contact with the exterior surface of the passage walls Various forms of construction and arrangement have been designed in radiators of this type, the radiator being usually built up of sheet metal blanks or units bent to the required shape, many of which have proven unsatisfactory owing to the expense of manufacture and also to fragility due to the necessary use of thin light metal and the stretching or creasing of the metal blanks in giving them form resulting in weakening of the metal usually in angles or bends.

It is the object of this invention to provide a construction in radiators having vertical Zigzag water passages in which said passages are formed by a pair of corresponding corrugated sheet metal blanks arranged back to back, so that a single pattern will serve for both walls of the passages, and to provide means for spacing and bracing the side walls of adjacent water passages to form ample air passages therebetween and obtain a substantial structure.

Another object is to provide the corrugated blanks and a spacing blank which may be readily assembled and soldered together, and in which the adjacent blanks will be interlocked at their points of contact to form a strong and durable joint not liable to pull apart, and also facilitate putting the parts together. j

Another object is to so form the water passage walls as to obviate the collection of sediment thereon to a large degree and minimize clogging of the passage.

Another object is to provide air passages formed between spaced adjacent water passages by the side walls of the latter of such configuration as to insure a free flow of air therethrough yet deflect the air currents within the air passages in such manner as to obtain a high cooling effect.

Another object is to provide a sheet metal blank for forming radiator sections with large zigzag water passages without creases or sharp angles which would weaken the structure and afford lodgment for foreign substances.

Other objects will appear hereinafter.

The invention is illustrated in the accompanying drawings, in which: 7

igure 1 is a detail in perspectiveshowing a portion of the front with parts broken away.

Fig. 2 is a detail in cross section showing the construction and arrangement of the air and water passages and illustrating the several blanks in section.

Fig. 3 is a detail in perspective of the partition or fin. Figs. 4 and 5 are views in perspective showing the opposite sides of the blanks 4 forming the water passage walls; Fig. 4t showing the inner face; Fig. 5 the outer face of one of the walls. i

Fig. 6 is a detail horizontal section as. seen on the line AA of Fig. 1, illustrating in plan the manner of arranging the blanks forming the water passage walls between the spacing blanks.

In carrying out the preferred embodiment of the invention, the spacing and bracing partition blank 6 is formed of a strip of sheet metal having V-shaiped corrugations extending transversely thereof. The apex 7 of each corrugation is formed with a longitudinally extending depression or channel 8 extending throughout the greater part of its length with the ends of the depression converging to the edges of the fin so as to retain the \l-shape of the corrugation at the edges of the sheet. I

The blank for forming the water passage walls comprises a sheet 9 of sheet metal formed with transverse V-shaped corrugations the walls of which are slightly longer from the base to the apex of each corrugation than the walls of the c0rrugations on the spacing blank so that normally the space between the corrugations on the walls 9 are wider than the spaces between the corrugations on the blank 6. In order to strengthen the sheet. 9 and to add rigidity thereto the metal at the ends of alternate corrugations is pinched. together to end of the radiator form horizontal fins 10 which serve to 'contract the corrugations so that they will conthe corrugations as particularly shown at. a in Fig. 2, and roundlng 'thecorrugation apex; the rounded portion of the apex pro jecting slightly beyond the pinched ends of the. corrugations as shown in Fi 6. 1 In assembling the radiator the sheet 9 is placed against the blank (3 as shown in Figs/2 and 6 with the fins 10 seating on the ends of the corrugations of the blank 6 and the rounded portions of alternate corruga ions seating in the depressionffl as shown in Fig. 6

The waterchannel 11 is formed by disposing a pair of the sheets 9 back to back; theends of the corrugations closely fitting together and joined by dipping insolder. A zigzag water passage will then be formed between the connectedwalls as shown in Fig. 2. The fins 10 will then project horizontally from the opposite sides of the walls of the water passage in staggered relation to each other and the outer edges ofthe corrugations will register with'and extend into the depressions 8 forming an interlocking engagement with the corrugations of the spacing blanln o The edges of the corrugated sheets and blanks are arranged flush and will form honeycombed openings on the inner and outer faces of the radiator through which air is directed through air passages 12 formed between the adjacent sheets 6 and blanks 9.

One side of the honeycomb openings leading to the air passages are formed by thespacing blank and the'other is formed by one of the sheets constituting the side wall of the water passage; The horizontal fins 10 form the top and bottomportions of the openings. A hexagonal opening is thus constructed but it is manifest that other shapes may be provided by'forrning the ends of the corrugations at the edges of the sheet as desired.

In forming a 'fin 10 by pressing the sides of a corrugation together an inclined face 13 is formed at the base of the fin forming a slightly convergent wall at the extremities of the air passage 12 which serves to deflect air currents entering the honeycomb openings so as to enhance the cooling action.

It will be noted that the cross sectional area of the air passage is less than that of its open end so that the flow of air entering the passage under force will be accelerated in traversing the passage which further hastens the cooling action.

Bybowlng thesidesof the corru'gatlons 1n the sheets forming the walls of the water passages these passages diverge between the flat, they would befree/to vibrate in and out like a diaphragm by the pulsations of the water but by forming the wall of each corrugation with an outward bend it will retain this curvature and will hot spring back on reduction of pressure in the water column.

In a radiator of the honeycomb type, a pair of corrugated sheets having their edges contracted forming fins on the apeXes and at the ends of alternate corrugations on one side of each sheet whereby the ends of the 'corrugationsare reduced, relative to their intermediate cross section, the intermediate walls of the corrugations being bowed, said sheets arranged back to back with their edges connected forming a vertical zigzag water passage therebetween with. outwardly and oppositely bowed side walls and dispos ing the fins in staggered relation to: each other on opposite sides of the walls, and a corrugated spacing blank having depressions in the apeXes of the corrugations adapted to receive the apexes of the filmed corrugations on the sheets forminghoneycomb air ducts, the fins abutting against the corrugated blank at the ends of the depressions and secured thereto.
